I'd say this is the best suggestion anyone could offer, rather than making it easier, just give players the ability to start from the second part of the fight once they've reached that far. This would allow them to learn that part without having to go through the issues of Party Drama from having to start over after failing when reaching said part. Would ease that Stress for the overall group while giving them the opportunity to focus on just that phase without having to repeat the phase before it.
